Laws were changing in the US at the time to amber signals. Some manufactures used amber bulbs behind clears lens until changing to amber lens.
I would guess some number of 289 Cobra owners changed from clear to amber lens.
Clear was most Cobras. A few scattered cars (including one of the SA team racers) received amber lenses but there seems to be no pattern of why or when. Amber was standard for 427 Cobra street cars. The is also a red lens that some other types of cars used as brake/marker lights.
